The present work focuses on the influence of solid-state welding, namely, friction stir welding (FSW) and arc welding, namely, metal inert gas welding (MIG), on the mechanical characteristics of new lightweight 5 mm thick Al-Mg-Mn alloy plates with the addition of 0.4% Sc and 0.1% Zr. The alloys were fabricated using aluminium with 10% magnesium, aluminium with 2% scandium, and aluminium with 5% zirconium master alloys in combination with the Al-Mg-Mn alloy- with the help of a stir casting melting technique. The hardness, tensile strength, 3-point bend strength, impact strength and microstructure of the rolled Al-Mg-Mn alloy plates with the addition of 0.4% Sc and 0.1% Zr were examined. Both the mechanical properties of the FSW and MIG weld joints were compared with those of the non-welded plates. The strength of the non-welded Al-Mg-Mn-Sc-Zr alloy plates was greater, than that of the FSW and MIG weld joints. However, the friction stir welded joints exhibited the improved mechanical properties in comparison with those the MIG welded joints due to more refined precipitation. Compared with the non-welded Al-Mg-Mn-Sc-Zr alloy plates, the friction stir welded joint exhibited a 91.6% joint efficiency and a 63.8% metal inert gas welded joint.

“…On the other hand, the TIG welded Al-4.2Mg-0.6Mn-0.4Sc-0.1Zr alloy exhibited the following mechanical properties: hardness (94 VHN), ultimate tensile strength (157.86 MPa), bending strength (3215 MPa), impact strength (3.8 KJ/m²), and elongation percentage of 4.6. Comparatively, the TIG welded alloy achieved 32.3% hardness, 39.3% ultimate tensile strength, 7.6% bending strength, 24.8% impact strength, and an elongation percentage of 66.2% when compared to the non-welded Al-4.2Mg-0.6Mn-0.4Sc-0.1Zr alloy [29,30]. These findings highlight the significant advantages of friction stir welding in terms of improved mechanical properties and performance of the Al-4.2Mg-0.6Mn-0.4Sc-0.1Zr alloy compared to TIG welding and the non-welded state.…”

This study investigated the mechanical and corrosion properties of Friction Stir Welded (FSW) and Tungsten Inert Gas (TIG) welded phosphor bronze (CuSn4) joints. Corrosion tests were conducted on the welded joints, and the percentage of weight loss due to corrosion was measured at different time intervals. Results revealed that the percentage of weight loss due to corrosion of the TIG joint increased with time, whereas the percentage of weight loss due to corrosion of the FSW welded joint remained constant. This could be attributed to recrystallisation that happened in the solid-state welding, which reduced corrosion in the FSW welded joint. In addition, tensile tests were conducted to evaluate the strength of the joints. FSW with a spindle speed of 1300 rpm, weld speed of 0.06mm/sec, plunge depth of 0.25mm, pin profile of pentagon, and flat shoulder profile was found to produce good results. TIG welding with a welding speed of 1.75mm/sec, a gas flow rate of 7.5 cm3/min and an amperage of 120A also produced good results. The tensile strength of FSW was found to be approximately 1.6 times higher than that of TIG welding.
